2004-07-29 Michael Natterer <mitch@gimp.org> Replaced the concept of having a boolean indicating if an undo step dirties the image by a bitfield indicating which parts of the image are dirtied: * app/core/core-enums.[ch]: reordered two values in enum GimpUndoType, added GIMP_DIRTY_IMAGE_SIZE to enum GimpDirtyMask. The values of GimpDirtyMask are still questionable and will probably change... * app/core/gimpimage.[ch]: removed signal "undo_start" and added a GimpDirtyMask parameter to the "dirty" and "clean" signals. * app/core/gimpimage-undo.[ch] (gimp_image_undo_push): replaced "gboolean dirties_image" by "GimpDirtyMask dirty_mask" and pass it to gimp_image_dirty(). (gimp_image_undo_group_start): added *ugly* code which tries to figure GimpDirtyMask from the group's GimpUndoType and store it in the GimpUndoGroup. Call gimp_image_dirty() instead of the removed gimp_image_undo_start(). This means the undo group now dirties the image just like one of its undo steps, but that's no problem since undoing cleans it in the same way. * app/core/gimpundo.[ch]: s/dirties_image/dirty_mask/g (gimp_undo_pop): emit clean/dirty signals *before* performing the actual undo step so listeners can detach from the image before it is changed by undo. * app/core/gimpimage-undo-push.c (gimp_image_undo_push_*): pass a GimpDirtyMask instead of TRUE/FALSE to gimp_image_undo_push(). * app/core/gimpimagemap.[ch]: removed "gboolean interactive" because it makes no sense to use GimpImageMap noninteractively. Don't freeze()/thaw() undo while the image_map is active which fixes many ways of trashing the image's undo state but probably introduces new ways of doing evil things. * app/display/gimpdisplay-foreach.c * app/display/gimpdisplayshell-handlers.c: changed according to the GimpImage::clean()/dirty() signal changes. Small fixes in the quit dialog's dirty image container. * app/tools/gimptoolcontrol.[ch]: added member and API to set/get the dirty_mask. * app/tools/gimpcroptool.c * app/tools/gimpimagemaptool.c * app/tools/gimpiscissorstool.c * app/tools/gimptexttool.c * app/tools/gimptransformtool.c: whenever setting "preserve" to FALSE, also set a "dirty_mask" which specifies on which image changes the tool wants to be canceled. * app/tools/tool_manager.c: removed "undo_start" connection and connect to both "dirty" *and* "clean" to check if the active_tool needs to be canceled. Cancel the tool only if the dirty_mask passed in the signal has common bits with the tool's dirty_mask. Fixes bug #109561 and probably opens some new ones...
